REINFORCED-CONCRETE CURB STRUCTURE.

Application filed January i5, 1919.

Toy all whom it' 'may Gnner/n Be it known that I, THOMAS IV. KELLY, a citizen of the United States, and a resident of Indianapolis, county ofMarion, and State of Indiana, have invented a certain new and useful Reinforced-Concrete Curb Structure; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying' drawings, in which like numerals refer to like parts.

This rinvention relates to reinforced concrete curb structures and is designed. primarily for use in connection with roadway andrstreet surfaces and the like.

The prime feature of the invention is in providing supporting legs for the curb structure whereby the common expedient of forming an enlarged and expensive base for supporting the curb and holding the saine in true alinement, is dispensed with.

A further feature of the invention is in so constructing the supporting legs and curb that said parts will be integral and form a monolithic structure.

A further feature of the invention'is the provision of reinforcing members which are embedded in the concreteV structure and which prevent cracking and disintegration of the parts.

A further feature of the invention is in so positioning` the supporting legs that they will resist strain in all directions.

A further feature of the invention is in so forming the openings to receive the legs that' projections will be formed on parts of the legs when formed which serve as anchors.

A further feature of the invention is in so constructing the top surface of the curb that the road surfacing material will interlock with the top ofthe curb when placed thereover and hold the surfacing material against creeping action,

In addition to employing the legs for supporting the curb structure they may be arranged to support platforms upon which heavy machinery may be placed and also columns upon which posts or the like may be supported.

In the drawings, which are made a part of this application, Figure l is a transverse sectional view through a curb showing the saine applied to use. Fig. 2 is a side elevation thereof. Fig. 3 is a top plan view. of a portion of the curb. Fig. 4 is a view Specification of Letters Patent.

similar to Fig. l showing a single supporting leg for the curb. Fig. 5 is a modified form of curb structure such as is used primarily f or holding brick surfaces in position. Fig. 6 is a side elevation thereof. Fig. 7 is a top plan view thereof. Fig. 8 is a top plan view of a post or pole supporting base. Fig. 9 is a side elevation thereof. Fig. l0 is a top plan view of a base such as is used for supporting heavy machinery or the like and Fig. 1l is a side elevation thereof.

Referring to the drawings, in which similar reference numerals designate corresponding parts throughout the several views, l indicates surfacing material such as is commonly used in constructing roadways, and particularly in country districts, and 2 indicates the curb which is positioned along the edges of the roadway to hold the material forming the roadway and surfacing material in proper position, said curb being preferably constructed of a composition of matter such as concrete or the like. Heretofore it has been customary to form an enlarged base portion on the curb structure in order to properly hold the same in alinemeiit and against lateral movement,

thus entailing a great deal of expense, and at the saine time not producing an entirely satisfactory structure. In the present instance the curb proper is merely of sufficient depth to properly retain the surfacing material in position, and is supported and maintained in perfect alineinent by means cf integral supporting legs 3, which are likewise' formed of the saine material of which the curb is formed, and as these parts are constructed at one operation a perfect monolithical structure is produced. There are preferably two or more legs grouped together and said legs are disposed at an angle to each other so as to produce a brace against each other, and thus resisting strain from any direction which may be directed against the curb, or as shown in F ig. 4 of the drawings where the curb is so constructed as to receive very slight strain a single post may be provided, in which instance the post preferably descends in a straight line from the curb. The legs 3 are preferably provided with enlarged vconical bases Ll, and the surfaces thereof are preferably provided with one or'more projections 5 whichv serve to anchor the legs and prevent longitudinal moveinent thereof.

V Thecurb 2 and the legs 3 are additionally:v Y reinforced by introducing rods 6 lengthwise `Y extending over the rods' embedded in the.

curb. vThe curb 2 is additionally reinforced at apoint midway between the'sets of legs by forming lateral extensions 8 on the side faces of the curb, and transversely throughthe curb and through the lateral extension reinforcing r0ds9 are placed.

It has been found in practice that the surfacing material, such as asphalt or the like, has a tendency to creep or spread out, due to various canses, and to overcome this objectionable feature the top surfaceV ofthe curb'is provided with a plurality of channels 10 and 11, the channels lOpreferably extending'diagonally across the top surface ofthe curb and in opposite directions, while the channels 11 extend parallel and longitudinally of the curb, although it will be understood thatsaid channels may be arranged vin any preferred manner.' In ordei to positively interlock the surfacing material with the curb, the channels are preferably formed at anA angle in' cross section to the vertical plane of the curb, thus pro- Y viding a substantially dove tail-groove, and

as the surfacing material is placed over the roadway or Athe curb whilerin a softened estate, portions thereof will enter the chanjnels and when it becomes set or hard Vwill positively interlock with the channels, ow-` ing to the overhanging wall ofrerach channel, thus securing a dove tail connection between the top ofthe curb and the surfacing material and rendering it impossible for the surfacingmaterial-to become loosened from the curb or to have creeping` or other movement thereon.

In Figs. 5, 6 and 7 a form of curbing such Yas is to be Yused for holding brick surfaces or the like in position is shown and in this instance the curb proper 12 isA preferably shaped similar to a plankand -is placed edgewise to the surfacing material 13, and is supported by forming posts 14 integral with the curb 12. The posts 14 are prefer# ably semicircular in cross section and reinforced by means of rods 15, while'the curb 12 is likewise reinforced by means of rods 16, and the posts are also'preferably provided with anchoring projections 17.

In Figs. 8 `and 9 a structure such as is ein; ployed for supporting columns, posts, telegraph poles and the like is shown, consisting of a` circular base'18 from which radiate legs 19, and in this instance Yeach basev is pro'- Y vided with Vfour of the legs, although a Vgreater or less number may beemployed if preferred;7 and" the legshaving reinforcing rods 20'the same as shown in the other structures. V1V

1n Figs. 10 and 11 a platform or'foundation structure v211is shown such Vas is employed for supporting heavy machinery and the like, andl in this instance a number of legs V22 are shown v:Vttjeachcorner of the platform, saidI legs-serving 4to'support the platform and to hold the same lagainst lateralmovement. 'Y

lln constructing the curb, particularly that form shown in F igs.` 1 to 4 inclusive, the Y gravelor macadam road bed is first prop'- erly shapedY and rolled 'until the proper plane or level has been reached, or imtil it has been properly shaped to receive the usual surfacing material. The parts of the roadway upon which thecurbproper is'to portions of the curb, suitable vtools beingemployed for this operation, yand such tools may be soarranged as to make the spaces in which the base'` portions and projections on the legs VVwill extend ifjsuchV are desired.

A Vframe for forming the curb then placed' on the rolled surface and the reinforcing rodsl entered into position, after which the material of which the curb and legs is: formed is poured into the mold and into the.l openings made to form the legs ofthe curb and as saidy material is in a plastic'condition, parts thereof will enter the enlarged portion of said holes and` formy vthe flanged base and the projections on the legs, consequently when the material hardens, the leg portions will be firmly anchored in the ground.

' As previously'stated, there are preferably two or more legs grouped together and these legs are disposed at an angle to eachy other and to the curb proper, consequently said legs will form a perfect anchor for the curb and prevent any movement thereof incident to strain or otherwise. After the curb is properly set or solidied, the roadway `is constructed between the curb and the surfacing material-then appliedithereto, said surfacing material, when. placed over the top of the curb, interlocking with the channels therein, and if desired lthese channels may be formed on the'A surface of the roadway proper so that the surfacing material will los lie

be interlocked throughout the extent of the 1. A monolithic ystructure includingV a body portion, a plurality of supporting legs integral with the body portion and said legs being disposed at Various angles for resisting the strain from all directions.

2. A curb structure, including a curb proper, and two or more integral legs depending therefrom and at opposed angles, said legs being arranged to resist strain on said curb from either direction.

3. A curb structure including a curb proper, integral legs depending from the curb and arranged in pairs, said legs eX- tending outwardly at an angle to the Vertical plane of the curb and at an opposed angle to each other, and a reinforcing rod extending lengthwise of said legs and through the curb and embedded therein.

1l. A ou'rb structure, including a curb proper, legs integral therewith and depending therefrom, and anchoring projections formed on the exterior surfaces and lower ends of said legs.

In witness whereof l have hereunto aflixed niy signature.
